DHG Filters WITH FILTER W/O FILTER DHG FILTERS Light incidence on a glass surface causes a loss of app.

In order to avoid dull images, the filter surfaces are treated with a metal oxide layer, also known as "coating".

High-end quality filters come with an additional Nano coating to make them liquid and dirt repellent.

3 DHG Filters WITH FILTER W/O FILTER DHG FILTERS Light incidence on a glass surface causes a loss of app. 5% of the light by reflections; contrast brilliance and sharpness are reduced. In order to avoid dull images, the filter surfaces are treated with a metal oxide layer, also known as "coating". High quality filters boast of a number of coating layers = Multi Coating. As an effect, reflections are almost eliminated. High-end quality filters come with an additional Nano coating to make them liquid and dirt repellent. They are easier to clean more robust than other filters WITH FILTER Quality Features of DÖRR DHG Filters DHG stands for Digital High Grade DHG Multi Coating on both sides ensures 99,5 % light transmission and avoids reflections, loss of sharpness, contrast and brilliance. Number of coating layers for DHG filters are: 10 layers, Super DHG filters: 12 layers. Ultra slim frame avoids vignetting when taking wide-angle pictures Black coated metal frame and black glass edges reduce reflections inside the filters W/O FILTER 03

DHG ND8 & ND32 Neutral Density Filters DHG ND8 NEUTRAL DENSITY FILTER The DHG ND8 neutral density filter extends the exposure time by factor 8, which corresponds to 3 aperture stops (f-stops).

DHG ND32 NEUTRAL DENSITY FILTER The DHG ND32 extends the exposure time by a factor of 32 and thus allows to extend the exposure e.g. from 1/1000 s to 1/30 s. This corresponds to 5 aperture stops, e.g. from f16 to f2.

6 DHG ND8 & ND32 Neutral Density Filters DHG ND8 NEUTRAL DENSITY FILTER The DHG ND8 neutral density filter extends the exposure time by factor 8, which corresponds to 3 aperture stops (f-stops). Example: the surrounding light conditions allow an f-stop of f8.0, it can change to f2.8 using the DHG ND8 filter so you can reduce the focus range for more creative shots. DHG ND32 NEUTRAL DENSITY FILTER The DHG ND32 extends the exposure time by a factor of 32 and thus allows to extend the exposure e.g. from 1/1000 s to 1/30 s. This corresponds to 5 aperture stops, e.g. from f16 to f2.8 So you can reduce the focus range or you get a dynamical motion blur with strong ambient light.

DHG Variable Neutral Density Filter DHG ND2.5 - ND500 VARIABLE ND FILTER The DHG Vario-ND2,5-500 variable neutral density filter shades the image even and colour neutrally.

7 DHG Variable Neutral Density Filter DHG ND2.5 - ND500 VARIABLE ND FILTER The DHG Vario-ND2,5-500 variable neutral density filter shades the image even and colour neutrally. By turning the filter, the shade intensity is infinitely variable. Exposure time can be expanded variable. Exposure time can be expanded from 2,5x to 500x corresponding to 1,3 to 9 aperture stops. The DHG neutral density filters ensures optimum contrast and brilliant images granted by the DHG coating on both sides. The slim filter frame avoids vignetting when using wide-angle lenses. Colour neutral due to neutral density Optimizes contrast results of your digital camera Reduces the depth of field without overexposure Non-reflective ultra slim frame avoids vignetting DHG Multi Coating on both sides WITH FILTER VARIABLE DENSITY FILTERS There are situations in which a photographer desires a longer exposure time, e.g. to create pictures of the sea or floating water or to eliminate people on vivid square. The aperture settings can come to its limit sometimes. No matter if in a studio or outdoors too much light does not allow a portrait shot with reduced depth of field. A variable neutral density filter shades the image even and colour neutrally. By turning the filter, the shade intensity is infinitely variable. Exposure time can be expanded variably , , , ,00 07
